A Jewish boy was serving the Prophet (PBUH). He fell ill, so the Prophet (PBUH) came to visit him while he was dying. He called him to Islam. The boy looked at his father who was sitting by his head, and his father said to him: Obey Abu Al-Qasim. So he embraced Islam then he died. The Messenger of Allah (PBUH) went out saying: Praise is due to Allah who saved him through me from the Hellfire.

Allah says: O son of Adam, I asked you for food and you did not feed Me. Son of Adam will say: O Lord, how did you ask me for food and I did not feed you, when you are the Lord of the worlds? Allah will say: Did you not know that my slave so-and-so asked you for food and you did not feed him? Did you not know that if You had fed him, you would have found that with me? O son of Adam, I asked you for [water] to drink and you did not give me [water] to drink. Son of Adam will say: O Lord, how can I give you a [water] drink when you are the Lord of the worlds? Allah will say: Did you not know that my slave so-and-so asked you for [water] to drink and you did not? Did you not know that if you had given him [water] to drink, you would have found that with Me? O son of Adam, I fell ill and you did not visit me. Son of Adam will say: O Lord, how can I visit you when you are the Lord of the worlds? Allah will say: Did you not know that my slave so-and-so was ill and if you had visited him, you would have found that with me, or you would have found me with him?
